Ko has work to do

Rio 2016 Olympics - The New Zealand golfer Lydia Ko struggled to light up the Olympic Golf Course once again this morning with a quiet second round of one under par.

With just two birdies and a bogey, the World No.1 has lost distance on the leaders and now sits seven shots behind South Korea's Inbee Park.

"I hit my tee shots really well but it's disappointing when you are not holing many putts out there," said Ko.

"I made good birdies on 15 and 16 to make me under par for the day, but when you are not holing many putts it can get a little frustrating."

Ko still remains positive leading into the final two rounds, but is also realistic about the challenge that now lies in front of her.

"The big key for me is to stay confident and focus on the shot in front of me. At the end of the day, all I can do is my best."

"I feel there's a lot of golf still to play. I know there's a lower number than what I have shot the last two days and hopefully that comes soon."

The 19-year-old has been struggling to start well throughout her Olympic campaign and this needs to change for her to have a chance at Rio glory.

"I've been playing the front nine over both days and when the girls are shooting low numbers, going into the back nine trying to make up for it is hard. I have to play the front nine a little better. If I put myself in a better position it puts less pressure on me going into the back nine."
